Commercial 3rd Party HMI
The BOR now had to make a decision about their second piece
for their system: the HMI
(Human-Machine Interface). Since they had
built their last monitoring system, the area of Human-Machine Interface had progressed
from character cell terminals to full, native, intuitive, graphical ones. This advancement
of technology had its pluses and minuses for the BOR.
| Pluses: the new interface was superior to the old one. |
| Minuses: the BOR’s schedule for completing their monitoring system was
too tight for them to take the time to construct their own interface. If they were going
to stay on schedule, they would have to search the market in hopes of finding an interface
flexible enough for their system. |
To their complete surprise and delight, Intellution had
just the user interface with the flexibility they needed: the FIX/32.
| The newest version of DDBS includes the following
components: |
| Front End processors provide the communications between the RAMS data base and the
external computer system, including the RTUs. |
| Optimization System receives instructions from area control centers and operators,
assembles information from the RTUs, and provides information and control to achieve
power, voltage, and water deliveries that meet system constraints. |
| Historian provides long term storage of operational data. |
| Distributed Data Manager System manages the question of the different nodes on the system. |
